PERMU'IATION-PADLOCK.

Application filed January 29, 1915.

To all whom 2'25 may concern:

Be it known that I, JosrrUA E.v RYoN, a citizen of the United States,residing at Desdemona, in the county of Eastland and State of Texas-haveinvented certain new and useful Improvements in Permutation- Padlocks,of which the following is a specification.

My invention relates to padlocks and more particularly to permutationpadlocks.

The primary object of my invention re sides in the provision ofa padlockof the character described wherein is provided a keyless locking meanswhich can be opened only by a certain combination or arrange ment of theoperating means, thereby preventing the surreptitious opening of thelook by unauthorized persons.

Another object of my invention resides in the provision of a lock casinghaving a shackle pivotally associated therewith, the latter beingengageable by novel retaining means positioned within the casing forremovably holding the shackle in engagement with the casing.

A further object of my invention resides in the provision of a novelactuating means mounted in the casing and associated with the retainingmeans for facilitating the actuation of the retaining means forreleasing the shackle from the casing.

A still further object of my invention resides in the provision of anovel means for mounting the actuating means, the latter beingpeculiarly arranged so as to necessitate a registration of the partspreparatory to the actuation of these parts as a whole for releasing theretaining means.

A still further object of my invent1on re-' sides in the provision of anovelly constructed resilient means that is associated with theretaining means on the shackle for facilitating the removal of theretaining means from the shackle when the lock has been operated and forautomatically causing the shackle to assume an open position whenreleased.

A still further object of my invention resides in the provision of adevice of the character described that is simple in construction,efficient in operation and one that can be manufactured and placed onthe market at a minimum cost.

Other objects as well as the nature, characteristic features and scopeof my invention will be more readily understood from the followingdescription taken in connection Specification of Letters Patent.

with the accompanying drawings and pointed out in the claims forming apart of this specification. I

In the drawings Figure 1 is a side elevational view of my inventionshowing to advantage the positioning of the actuating disks;

Fig. 2 is a side elevational view of the same with the cover removedshowing the shackle in a closed position;

Fig. 3 is a longitudinal sectional view of my invention through thecasing looking toward the cover showing the shackle in an open position,the parts being so arranged that this may be made possible;

Fig. 4: is a vertical sectional view taken on the line 4-ft of Fig. 2and looking in the direction in which the arrow points; and

Fig. 5 is an enlarged fragmentary sectional view of the actuatingmechanism.

Referring more particularly to the drawings in which similar referencenumerals designate like or corresponding parts throughout the differentviews, I provide a casing 1, formed preferably of metal and providedadjacent the upper end thereof with openings 2 and 3, the openingsreceiving the ends of the substantially U-shaped shackle 4. One end ofthe shackle 4 is pivotally mounted within the casing by means of a pin5, the extreme free end of the connect ing end of the shackle beingslightly enlarged and provided on its extreme under surface with arecess 6 and further provided adjacent the respective sides of therecess 6 with laterally extending lugs 7 both the recess and the lugsbeing for a purpose to be hereinafter described. The opposite end of theshackle 4 is provided with a recess 8, the latter forming a head 9 onthe terminal thereof, which head 9 is normally arranged in removableengagement with a complemental recess 10 of a tumbler 11. A head 12 isformed on the tumbler when the recess is provided, the head beingcomplemental to the recess 8 in the shackle 4c and both the re cesses 8and 10 and the heads 9 and 12 respectively in the shackle and tumblerconstitute a suitable catch for facilitating the removable engagement ofthe parts when desired. The tumbler 11 has its inner end curved as at 13and the extreme free inner end reduced to provide a shoulder whichlatter has bearing thereagainst the reduced end of a substantiallyarcuate lever 15. Likewise the reduced end of the tumbler bears againstthe shoulder provided by reducing the lever 15 and these parts are heldin rigid relation with respect to each other by a suitable fasteningdevice 14: the latter being pivotally mounted in the casing at a pointsubstantially intermediate its ends, by means of a pin 16. A projection17 is formed onthe arcuate lever 15 at a polnt adjacent the pivot pointand extends laterally from the lever for a purpose to be hereinafterdescribed.

In order to automatically force the shackle into an open position whenthe retaining means or tumbler has been removed from engagementtherewith in a manner to be hereinafter described, I have provided asu1t able elastic element preferably a leaf spring 18, the latter beingbent upon itself to a point adjacent one end thereof into a c rcularconfiguration as shown at 19, the circular portion being disposed abouta suitable pin 20 mounted in the casing. The arms of the spring aredisposed at substantially right angles to each other, the entire springassuming a substantially L-shaped form, the longer arm of the springextending across the casing and in engagement with the lugs 7 and therecess 6 on the inner end of the shackle, and the opposite or short armof the spring is engaged on the free end of the arcuate lever 15. Bythis arrangement it can be seen that the long-er of the arms exerts apressure which normally tends to force the shackle upwardly from thecasing, whereas the short arm exerts downward pressure on the arcuatelever and due to the fact that the same is in rigid engagement with thetumbler, the tumbler is normally held in yielding engagement with thefree end of the shackle 4 as clearly shown to advantage in Fig. 2 of theaccompanying drawings. It will be understood that the curved end of thetumbler 13 and the arcuate lever 15 are arranged in closely spacedrelation with the outer edge of the casing, thus providing a suitablespace in approximatelythe center of the casing for a'purpose to behereinafter described.

Secured to the casing by means of the pins 5, 16 and 20 is a cover 21,the latter being of a substantially circular configuration and havingthe upper edges thereof arranged in alinement with the outer edgesof thecasing. The cover is provided with a circular screw-threaded opening 22in which is removably received my improved operating means for releasingthe retaining means from engagement with the shackle.

The improved operating means in this in- 'stance consists essentially'ofa substantially circular plate 23, the outer perlphery of V which isarranged in screw-threaded engagement W'iththe opening 22, the platebeing provided with a centrally positioned opening in which is rotatablymounted a tubular 'mounted an actuating disk 25 having a pointer 26projecting from one point of the periphery for a purpose to behereinafter referred to. A supporting disk 27 is rigidly mounted on theinner end of the tubular shaft 24 and is positionedwithin the spaceprovided in the casing by the peculiar arrangement of the tumbler andarcuate lever. In order to hold the disk 27 in its proper position andin spaced relation with the plate 23, I have disposed a collar 28 aboutthe tubular shaft and the latter also constituting a bearing forsupporting the disk thereon. A stub shaft 29 is rotatably mounted in thesupporting disk 27 at a'point to one side of the center of the disk, thesaid stub shaft receiving a gear 30, the latter being arrangedinabutting relation with the disk and in rigid connection with the shaft.For the purpose of engaging the projection 17 carried by the arcuatelever for releasing the shackle from engagement with the tumbler in amanner to be hereinafter described, I' have rigidly and eccentricallymounted a disk 31 on the free end of the stub shaft 29,

the disk being so arranged as to project beyond the periphery of thesupporting disk 27 when desired so that the same may engage theprojection 17 In order to rotate the gear 30 and consequently rotate theeccentri-cally mounted disk 31, I have journaled another stub shaft 32inrthe tubular shaft 2e and rigidly mounted on the inner end of theshaft 32 a gear 33, similar in con- 10o struction with the gear 30. Thegear 33 is arranged in abutting relation with the supporting-disk 27 andhas the teeth thereof in mesh with the teeth of the gear 30 so that whenthe shaft 32 is rotated, a rotary movement is consequently imparted tothe eccentrically mounted disk 31 through the me dium of the gear 30.The outer end of the shaft 32 projects slightly beyond the outer edge ofthe tubular shaft 2% and receives a 11s disk 35 has its outer peripheryroughenedto 1 15 facilitate the rotation of the same. A pointer 36projects from the under surface of the disk 35 slightly beyond theperiphery thereof and when the same is in a desired position constitutesa suitable-means for deter 120.

mining when the parts positioned within the casing are so arranged as toactuate the re taining means in the casing. I v The outer surface of hecover 17 is provided with suitable graduations, the same beingpositioned about the actuatingdisks 25 and 35. 1

1 The operation of my invention is as folows:

Assumingthat the lock is. a'position as 13G,

shown in Fig. 2 and it is desired to open the same, all that isnecessary to do is to rotate the actuating disk until the pointer 26,which is arranged in substantial alinement with the eccentricallymounted disk, points in a direction toward the extreme lower end of thecasing or so that the eccentrically mounted disk 31 will be positioneddirectly above the projection 17 on the arcuate lever, thereupon theactuating disk 35 is rotated until the pointer 36 thereon assumes aposition of registration with the pointer 26. During the rotation ofthis part the gear 33 which is carried by the shaft 32 is also rotatedand imparting the rotary motion to the gear and consequently to theeccentrically mounted disk 81 and because of its eccentric mounting andthe fact that when rotated it projects beyond the periphery of thesupporting disk 27 it will engage the projection 17 on the arcuate leverand force the arcuate lever downwardly against the tension of the spring18 simultaneously causing the tumbler 11, which is in pivotal connectionwith the arcuate lever to be drawn inwardly from engagement with thefree end of the shackle 4. Because of the arrangement of the spring withthe shackle when the free end of the shackle is released the spring willautomatically force the free end of the shackle upwardly from thecasing, thus opening the look. In closing the lock all. that isnecessary to do is to rotate the actuating disk until the eccentricallymounted disk 31 is in removable engagement with the projection 17whereupon the shackle will be forced downwardly into engagement with thetumbler 11.

Although I have shown and described the preferred embodiment of myinvention, I desire it to be understood that I am not to be limited tothe exact details shown, however, great stress is laid upon thearrangement of the peculiar construction and arrangement of theoperating mechanism that is associated with the retaining means forreleasing the shackle.

From the above description taken in connection with the accompanyingdrawings, it can easily be seen that I have provided a device that issimple in construction, containing but a few simple parts that can becheaply manufactured and assembled and when assembled can be placed uponthe mar ket and sold at a minimum cost.

It will be understood that the above description and accompanyingdrawings comprehend only the general and preferred embodiment of myinvention and that various minor changes in detail of construction,proportion and arrangement of the parts may be made within the scope ofthe appended claims and without sacrificing any of the advantages of myinvention.
